One of the world's largest floating cranes is being used to move spans of the Spuyten Duyvil Bridge for upgrades.
The swing bridge, which carries Amtrak trains from Penn Station traveling along the Empire Corridor which spans as far as Canada, is being upgraded.
The bridge was severely damaged during Hurricane Sandy and suffered years of corrosion and electrical malfunctions.
Jason Abrams, an Amtrak spokesman, says New Yorkers deserve more reliable service.
"The upgrades will provide a smoother ride, and less slowing down because the infrastructure is going to be improved," Abrams says.
The bridge is slated to be set back in place by late August or early September, according to Amtrak.
